Soldering PCB's

[Deleted]

I'm just finishing up building the Pulse 2 PCB. Since I'll be using this detector around salt water, would it be a good idea to tin all the PCB copper lands?
Thanks

I would think the best approach would be to seal the Pcb with one of the many commercial sealant compounds, after the board has been soldered and tested. I believe Allied Electronics provides a line of sealants.

But Before Coating it with anything, Make sure ALL Solder Flux is REMOVED, on Both Sides of the Board.

Tinning the copper doesn't help much, as tin can also react with salt over time.
